Viewing the Data
SLIDE 20
How currently use it
- Deicing efforts
- Mobilize faster
- Proactively treat roads
- Target problem areas
- Alert travel public via CMS
- Internal alerts
- Reduce speed limit in VSL zone
- Data provided to public via NWS and News Stations
SLIDE 21
How could we use it?
- Change timing plans
- Better predicting and understanding of roadways
- Fog alerts
- Hydroplaning alerts
- Hurricane evacuation
SLIDE 22
Challenges
- GDOT Perception
- Alert Oversaturation
- Data Comprehension
- Personnel Access
- Data trust
- Public Perception
- CMS Messaging
- Date Comprehension
SLIDE 23
Moving Forward
- Data sharing with neighboring states
- RWIS Expansion
- GDOT
- Local Agencies
- Provide scaled down RWIS for
intersection use
